President Barack Obama said those responsible are yet to be identified, and cautioned that "people should not jump to conclusions before we have all the facts.

President Obama did not say whether the blasts were a terror attack. Shortly after the blasts, a fire broke out at a local library, raising suspicion of a possible third blast. However, Boston Police Commissioner Ed Davis later said that based on preliminary investigation, it came out that the incident at the library "may not have been an explosion (but) a fire." (Reuters)
The police also did not specify whether the two blasts were an act of terror. They said they do not have any suspect in custody and the FBI has taken over the investigation.
